What is the "two-second rule"?

The "two-second rule" refers to a guideline for maintaining a safe following distance between vehicles. This rule helps drivers assess how much space they should keep between themselves and the vehicle in front of them to ensure they have enough time to react in case of sudden stops or emergencies. By counting two seconds from when the vehicle ahead passes a fixed point, such as a sign or a tree, drivers can gauge an appropriate distance. If they reach the fixed point before counting to two, they are following too closely and should increase their distance to avoid potential collisions. This rule is particularly beneficial in promoting safe driving practices and reducing the risk of rear-end accidents.

The other options discuss different aspects of safe driving but do not relate directly to the concept of following distance.
